The good folks at Frontline Games did a kickstarter a few months ago for their new Dungeon Stones product and I jumped on board. I have have tinkered with Hirst Arts blocks and Dwarven Forge tiles in the past (and currently) -- each with their own strengths and weaknesses. Stones brings their own set of Strengths to the table. I'll try to get a review in later, but two of my favorite things are : 1) They are double sided! Its like getting twice the tiles for your buck! 2) They are made of the reaper bones material so they are easily modifiable

The above picture is what they look like out of the box and below I have added some pictures of my test tiles for color scheme. I'm still tinkering with this though. In case you are curious, all you need to do is wash them and apply the paint. I used dish soap and dumped them all into the kitchen sink. No primer is necessary!
